A movable pulley is not fixed at all points. It has one end attached to a fixed point, such as a ceiling or beam, while the other end is attached to the object being lifted. The pulley itself is free to move along the rope or cable, allowing for mechanical advantage in lifting heavy loads.
It is a line segment.
true
A sphere
A line in 2D and a plane in 3D A perpendicular bisector of the line connecting the 2 given points
It is the locus of all points such that their distance from a fixed line (the directrix) is the same as their distance from a fixed point which is not on that line (the focus).
Yes an elevator is a movable pulley!
a fixed pulley is a pulley that stays at one place to pick up an object. A clothes hanger is a fixed pulley.....this is all i know good luck...
It is a line segment.
The center of the circle. That's how the circle is defined. (The collection of all points on a plane equidistant from a fixed point. The fixed point is the center and the fixed distance is the radius.)
This set of points forms a circle with the fixed point as its center.
triangle
an ellipse.
That's false
A set of all points is how various shapes are made in geometry. Lines are sets of points, and so are surfaces. Circles are sets of all points that are a fixed distance from a central point. All geometric shapes are made from sets of all points.
